Physical Properties of Silica Modified HZSM-5 Zeolite
Abstract:
HZSM-5 zeolite was modified by silicone oil through chemical liquid deposition(CLD). The modified zeolite were characterized and examined by IR, nitrogen adsorption, and in the reactions of metaxylene isomerization and 1,3,5-triisopropylbenzene(1,3,5-TIPB) cracking. The results showed that the framework and micropore structure of HZSM-5 zeolite remained unchanged and the sizes of open pore in zeolite were reduced and the Brφnsted acidity values on external surface were inactivated. The mechanism of silica modification has been briefly discussed.
